Alright, here's the predicament. Have two 8 ohm cabs, both loaded with the same speakers and love 2x15 setups. However, the head is slightly damaged, the jack is busted and I've torn it apart and can't figure out why it's not working. I bought it this way for $20. Anyway, it's a Peavey Mark VI bass head, capable of 4 ohms, and I've got a pair of 8 ohm cabs I want to run. The second jack is busted, so would a Y-cable suffice to power both? Electronically, my math says this will work for 4 ohms, two 8 ohms in parallel. Would this work, or would I need something else?
